  1. BSOD irql_not_less_or_equal when playing videogames - Issues with cpuz149_x64.sys and...


    My PC is relatively new, and isn't bad at running games. Until recently I've had repeated blue screens when running my games, even at lower settings, and knowing that I'm not overclocking or overheating the PC whatsoever. I don't know what the issue is, I've scoured the web for an answer for so long now. It either involves cpuz149_x64.sys or ntoskrnl.exe, and is a driver issue. Though I don't know how to update the drivers at all for those. There doesn't seem to be a straight answer, and by checking files or scanning my hardware there is seemingly nothing wrong with this PC at all.

    It runs fine off of a game, and can handle things fine usually - However for whatever reason a game can only run for 20 minutes at a time before a BSOD rears it's head.


    Here are the two crash reports in case they are needed.

    BSOD IRQL_NOT_LESS_OR_EQUAL hall.dll ntoskrnl.dll

    Have you rebooted since uninstalling cpuz?

    cpuz149_x64.sys is still showing in the stack as being the cause.

    Path to driver - C:\WINDOWS\temp\cpuz149\cpuz149_x64.sys
